This article describes SNaG – Polish adaptation of Burris and Rempel’s Amoebic Self Scale, a 22 item standardized measure of individual differences in sensitivity to the boundary threat across thee domains. The three scales of SnaG are: Bodily, Social and Territorial-Symbolic. The SnaG was found to have internal consistency/reliability and validity. Generally, as predicted, SnaG’s subscales were associated with existing measures tapping hypochondriasis, depression, self-esteem, social anxiety, trait anxiety, normative identity, compass of shame and moral judgments.
